Hot Forming Sheet Metal

Parts produced by hot forming are characterized by high strength complex shapes and reduced springback effects.

Hot forming sheet metal.

645 naganathan a et al including altan t progress on fe simulation of the hot stamping process 3rd int. Hot forming has become increasingly important for the automotive industry in meeting specific requirements for lower overall weight and higher crash safety. In essence hot forming is a matched metal tool forming process that relies on time temperature and pressure. Depending on the product being formed those working directly with the product will determine the proper temperature.

High temperature alloys ideally suited for hot forming include. Transfer from furnace to press and drawing tool. Conference on hot sheet metal forming of high performance steel chs kassel germany june 13 16 2011. Spinning sometimes called spin forming is a metal forming process used to form cylindrical parts by rotating a piece of sheet metal while forces are applied to one side.

The part is then held under pressure for a period of time to finalize formation. Sheet metal forming is used for industrial manufacturing in many sectors from car door to tin can. It is performed by bringing the hot sheet metal into contact with the hot die while the hot punch descends into the die and shapes the part. The hot forming process consists of the following steps.

Hot forming is similar to cold forming but involves heating the tool used to handle the metal as well as the metal itself. A sheet metal disc is rotated at high speeds while rollers press the sheet against a tool called a mandrel to form the shape of the desired part. The hot sheet metal is brought into contact with the hot die whilst the hot punch descends into the die and shapes the part. In most cases a certain amount of elastic deformation leads to springback which occurs after forming is complete.

Heat treatment in furnace. Hot forming is a range of processes developed specifically for the forming of high temperature alloys. The desired shape is achieved through plastic deformation without undergoing any machining like milling. Hot draw forming the hot forming process is similar to traditional cold forming but involves heating the tool and component.

With this method parts are formed in their soft state at elevated temperatures and then quenched in the tool. Autoform s software enables you to simulate thermal effects in sheet metal forming. In sheet metal forming the final shape of a part is made from a flat metal sheet.
